Energy
About Energy
Energy is a minimalist logic puzzle game about routing electrical current from power sources to receiver nodes on a grid. Each level gives you a fixed set of wire segments, and your job is to connect every source to its matching receiver without crossing wires, exceeding your segment budget, or running into blocked grid squares.
The constraint system is where the depth lives. Crossings are forbidden, blocked squares create routing obstacles, and multi-source boards require planning the entire network before placing the first segment — backtracking is allowed but costs additional moves that may push you over the limit. What looks impossible at first glance usually has a solution that requires routing a wire in the opposite direction from your first instinct.
Solving Harder Levels
Work from the most constrained source-receiver pair first — the one with the fewest available paths. Once its route is fixed, the remaining paths become easier to plan because you know which grid spaces are already occupied. On large boards, sketch the rough route for every pair mentally before committing to placement. The levels in each difficulty tier are sorted roughly from easiest to hardest, so if a level in a group defeats you, try a later one in the same pack — the solution pattern sometimes illuminates the earlier puzzle.
